Interstellar extinction of classical Cepheids from neighboring stars I. Methodology and application to 16 Galactic Cepheids
Wilma Kiviaho, Pierre Kervella, Mika Juvela +21
Galactic Cepheid variable stars are fundamental calibrators of the cosmic distance scale through their Period-Luminosity (PL) relation. The high-precision parallaxes expected from…
Revisiting candidates for non-pulsating stars located in the Cepheid instability strip in the Large Magellanic Cloud
W. Narloch, C. Galan, G. Pietrzynski +5
We analyzed photometric and spectroscopic data for 11 candidates for non-pulsating stars located in the Cepheid instability strip (IS) of the Large Magellanic Cloud (LMC) in order…
HALO II: Constraining Hubble constant through continuum delay fitting of Fairall 9
Amit Kumar Mandal, Francisco Pozo Nuñez, Vikram Kumar Jaiswal +28
The Hubble tension remains one of the most significant unresolved problems in modern cosmology. A key question is whether it may arise from underestimated systematic uncertainties…
HALO I: Photometric continuum reverberation mapping of Fairall 9
Amit Kumar Mandal, Francisco Pozo Nuñez, Vikram Kumar Jaiswal +23
We investigate the origin of inter-band continuum time delays in active galactic nuclei (AGNs) to study the structure and properties of their accretion disks. We aim to measure the…
Blending-induced beating and emission in the symbiotic star Terz V 2513
J. Merc, J. Mikołajewska, C. Gałan +4
We present a detailed analysis of Terz V 2513 (=2MASS J17334728-2719266), a poorly studied symbiotic star. Our motivation was a peculiar beating pattern in its light curves from al…
Precise physical parameters of three late-type eclipsing binary giant stars in the Large Magellanic Cloud
G. Rojas García, D. Graczyk, G. Pietrzyński +17
Detached eclipsing binaries (DEBs) allow for the possibility of precise characterization of its stellar components. They offer a unique opportunity to derive their physical paramet…
Gaia18aen: First symbiotic star discovered by Gaia
J. Merc, J. Mikołajewska, M. Gromadzki +20
Besides the astrometric mission of the Gaia satellite, its repeated and high-precision measurements serve also as an all-sky photometric transient survey. The sudden brightenings o…
Chemical abundance analysis of symbiotic giants. I. RW Hya and SY Mus
J. Mikolajewska, C. Galan, K. H. Hinkle +2
The study of symbiotic systems is of considerable importance in our understanding of binary system stellar evolution in systems where mass loss or transfer takes place. Elemental a…
